Default True Dual Exhaust System

I currently have the sport 5.7L Hemi with dual out exhaust. I am looking to put on a true dual exhaust system. Does anyone know if this is okay or will it screw up the trucks computer system or something?

Thanks!

I'd think it can be done if a competent tech did the work. You're looking at two CATs, and two mufflers plus doubling the sensors (this is where the good tech comes in) plus telling the computer what's what.

If I were doing it, I'd also put a set of headers on. No sense in going to all that effort and expense and only doing half the job.

I know it has been done already. The gentleman has an 10' R/T. He took is truck into a local shop and showed them exactly how he wished to have it set up while it was on the lift. I forget the specific's as far as keeping/removing the cats, muffler and resonator's etc..I do know he is very pleased with the outcome and has not had any issues with drone or throwing codes. Brianwl is correct about having a competent tech do the install as the whole process is something that require's a seasoned professional's direction and fabrication.

Is there a HP gain to be had with true dual?

I would say there must be a gain of sorts. Better air flow can't help but increase performance. I'm just not sure what the numbers on the actual gain will be.

There's no need to double up on sensors since it already has 1/1, 1/2 ,2/1 and 2/2 sensors already in place.

I imagine you'd still want to add an X-pipe even if you run "true" duals, so is there really a gain? Or is it more of a bragging right? What if you just upgraded the stock Y-pipe? Just curious...

I'd hold off until you have heard that somebody has already done a setup like what you are looking at. The reason I say that is because you may actually loose some low-end torque because of the loss of back-preasure. I did this to a GMC a few years back and I felt the loss of low-end torque. Now once I got rolling, I felt the gain (40mph punch, merging, etc.). If you do go true dual, I'd upgrade the intake as well. If your going to flow better going out, you'll need to have better "flow" going in. Also, go with an x-pipe. I'm sure if you search on u-tube you'll find examples of all sorts of exhaust systems and tru-dual setups.
